Description
Technical field
The invention belongs to environment-protective process and apparatus field, be specifically related to a kind of device adopting biomembrane purification 3 benzene waste gas.
Background technology
Dyestuff, agricultural chemicals, production of flavor, make paint, spray paint, pharmacy, shoemaking, the industrial chemicals of the industry extensive use such as Furniture manufacture or solvent, they can produce organic exhaust gas in process of production, contaminated environment, special particularly benzene,toluene,xylene, industrially be commonly called as " triphen " waste gas, they are on the impact of nervous centralis, make people occur neural strong excitation or suppress performance, as restless, stupefied, drowsiness etc.; And the poisonous effect of dimethylbenzene is mainly divided into renal toxicity, embryo or genotoxicity and neurotoxicity.In recent years, 3 benzene waste gas was in the southeastern coastal areas, and particularly coastal shoemaking industry district, creates sizable environmental threat, and the acute and chronic intoxication accident of " triphen " happens occasionally.Compared with the physical-chemical process such as adsorption and purification technology, catalytic combustion purification techniques of routine, bioanalysis has the advantages such as equipment is simple, small investment, operating cost are low, non-secondary pollution, especially, when processing low concentration (< 0. 1%), bioanalysis has the unrivaled economy of additive method.But traditional bioanalysis, as bio-trickling filter and biofilter microflora, there is mass transfer area little, spatiotemporal efficiency is low, easily blocking and the large problem of vapour lock.
Summary of the invention
Goal of the invention of the present invention is the defect overcoming prior art, provides the suspended biological filter bed for the treatment of organic exhaust gas that a kind of efficiency is high.
For achieving the above object, the present invention adopts following technical scheme, a kind of suspended biological filter bed processing organic exhaust gas, comprise a container vertically arranged, the bottom of described container and top are respectively arranged with exhaust gas entrance and clean gas outlet, and the bottom of container is provided with mud discharging mouth, the sidewall of container is provided with nutrient solution and adds mouth, the inside of container is provided with nutrient solution, and be provided with plastics floating stuffing in nutrient solution, attached growth of microorganisms is on floating stuffing.
Further, described container entrance place is provided with aerator, regularly can strengthens aeration rate to stir packing layer, make aging biofilm detachment and fall to reactor bottom, then being discharged by mud discharging mouth.
Further, described floating stuffing is immersed in nutrient solution, is conducive to growth of microorganism and absorption organic exhaust gas.
Further, the filling rate of described floating stuffing is 10-80%.
Further, in described floating stuffing, be provided with deflector, be convenient to organic exhaust gas flowing.
Further, there is porous resin layer on described floating stuffing surface.
Further, described porous resin layer thickness is 1-5 mm.
Beneficial effect of the present invention:
1, by arranging aerator, regularly can strengthen aeration rate to stir packing layer, make aging biofilm detachment and fall to reactor bottom, then being discharged by mud discharging mouth, purification efficiency is high.
2, by arranging deflector, airflow smooth, improves purification efficiency.
3, by arranging porous surface resin bed, increase specific area is large, start-up is fast, biomass load is large, proportion is little, be easy to suspend in water, vapour lock is little, and can not block, energy consumption is low, media-filling rate is about 10% ~ 80%, voidage is large, and spatiotemporal efficiency is high, and floor space is little.
